Male osteoporosis associated with longterm cyproterone treatment
1Department of Rheumatology, CSB, Hope Hospital, Salford, United Kingdom.
Abstract:
A 58-year-old man with previous dorsal vertebral fractures was referred for continuing management of osteoporosis. He was treated in the past with cyproterone acetate for hypersexuality. There were no other risk factors for osteoporosis. A dual energy radiographic absorptiometry scan confirmed osteoporosis. Treatment with alendronate 10 mg/day improved bone density and back pain. Patients receiving longterm treatment with cyproterone might be at risk for developing osteoporosis and would benefit from regular bone density monitoring.

Bone Remodeling
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
